BinaryFilterCommand Constructor(bool,int[])

Summary

Initializes a new BinaryFilterCommand class object with the specified parameters.

Syntax

Objective-C

C++

Java

public BinaryFilterCommand( 
   bool maximum, 
   int[] matrix 
)

Public Function New( _ 
   ByVal maximum As Boolean, _ 
   ByVal matrix() As Integer _ 
)

- (instancetype)initWithMaximum:(BOOL)maximum 
                         matrix:(nullable const int *)matrix 
                   matrixLength:(NSUInteger)matrixLength

public BinaryFilterCommand( 
   boolean maximum,  
   int[] matrix 
)

public: 
BinaryFilterCommand(  
   bool maximum, 
   array<int>^ matrix 
)

Parameters

maximum
Value that represents the maximum value.

matrix
Array of filter coefficients.

Remarks

Set maximum to true to erode black objects and false to dilate black objects. The dimension value is the size of the rows and columns of the matrix.

Example

Runs the BinaryFilterCommand on an image to dilate black objects.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void BinaryFilterConstructorExample_S2() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command

   MessageBox.Show("The dimension property has the value = " + command.Dimension.ToString()); 
 
}
